When to transfer quarantined fish?

I've had rainbow threadfins in a quarantine tank since September 25th.
About a week and a half ago, one male died. I found him stuck in a plastic tree. I believe he might have died either because I didn't change the tank water often that week or there is one fish which bullies the other males. He chases them around the plastic tree decorations. I was thinking he might have chased him into the tree and he got stuck. But then again, I'm no expert.

So my question is: when is it safe to transfer the fish to my display tank? Should I still wait as one died about a week and a half ago? What should I be looking for before transferring them?

Thanks!

You have them quarantined them for 3 1/2 weeks. One dying might not have been from a disease, maybe just died... Its possible they got stuck, but that wouldn't have killed them. It might just have hurt them. I would quarantine till 4 1/2 weeks(until next week). Good luck!

 

I agree with above, prolonging the quarantine won't hurt and will rule out any possibilities it was due to infection. Have you also medicated for parasites and the like during the quarantine?

Oh no, I thought I replied. Thanks for your advice!

No, I was going to add salt to the water when the fish arrived but was advised not to if everything seemed fine.

 

I'm getting ready to transfer my 7 Rainbow Threadfins to my display tank. They've been in quarantine since September 25th.

I actually started with 8 but one male died about 3 weeks ago. I suspect he either died from me not changing the water as often that week or something to do with being bullied by one of the other males. All of the others seem fine.

Just a few questions to make sure I'm doing this right:
-What should I look out for that could possible signal that it's not a good idea to transfer them to my display tank yet? For example, I've never really looked for any specific signs of illness. I've just checked the fish every day to make sure that they're alive, swimming around, eating, etc.

-Is there a chance that the fish can get stressed out from the transfer from one tank to another and then become ill in the display tank?

-I hope this isn't too obvious- now that I'm removing the fish from quarantine since they seem fine, can I use tools that I would use for my display tank when doing the transfer? For example: I think I'll add some of the tank water from the display tank into a bucket that I use when I add water into the display tank and place the threadfins in there when transferring them.

-The temperature for the quarantine tank reads around 78 degrees while the display tank reads 79/80. Is this a big deal?

Thank you!

 

I would look for white spots, discoloration, red patches, and injurys. Also look for little red worms sticking out of the fish’s butt. The worms, known as camallanus worms are very common and often aren’t seen in quarantine because they’re so small and hard to see.

 

Half display tank water and half QT water should get the temp close enough. What about all the other parameters? How close are they to the same in both tanks? If the new fish aren't showing any kind of disease I would think it would be safe to use the same equipment to make the transfer.

When I brought my bloodfin tetras out of quarantine I just netted them straight over to their forever home. Both tank were side by side so no need for a container to carry them in. Parameters were the same in both tanks. BTW: These were the first fish I had ever quarantined. Really the only reason I did it this time is because my grow out tank needed an ammonia source.

Thanks so much for your advice.
When I set up my original display tank I of course made sure it was cycled (took about 2 months or so) and kept testing the water for ammonia, nitrites, and nitrates.

For the quarantine tank- I was advised to just change the water every other day which I have been doing. I also have a sponge filter. I really haven't tested the water so I will do that today.

Does it make sense that the tank is already cycled as it has been going since end of September and has had fish in it since the start of setting it up?

Some of the threadfins have a teeny black dot on their mouths. Is that normal? Had it ever since I can remember.
They look fine otherwise.

You are so very welcome.

It is possible but only the tests can tell us for sure.

I don't know about the black dot as I've never owned or even seen them in other than photos.

When I set up my display tank I of course cycled it and was testing the water a few times every week.

For the quarantine tank, I was advised to just change the water every other day. That's exactly what I do. I also have a sponge filter going. I've never actually tested my quarantine tank water as I change it frequently. I will test today.

Since my tank has been running since end of September with fish in it since then could it be fully cycled?
